-LRB- CNN -RRB- -- Ryan Giggs ' career as a player-manager got off to a winning start as Manchester United defeated relegation-threatened Norwich City at Old Trafford .

The United legend is temporarily at the helm of the Red Devils after David Moyes was sacked on Tuesday .

Giggs chose not to select himself for his first game in charge and instead watched from the dugout as his side , which bore six changes from last week 's loss at Everton , cruised to a comfortable 4-0 victory .

Wayne Rooney opened the scoring from the penalty spot after 40 minutes and then added a second two minutes after the break .

Substitute Juan Mata knocked in a Phil Jones center after 62 minutes to make it three before stooping to claim his own quickfire brace after Lucas Antonia Valencia rifled across goal 10 minutes later .

The win matched United 's biggest victory of the season and saw the them register more shots on target than in any other league game under Moyes .

Speaking to Sky Sports after the game , Giggs revealed he had struggled to sleep the night before and dreaded telling the players who would miss out of his team selection .

`` Leaving the likes of Juan Mata out of the starting 11 was difficult and a position I 've never been in before . I 'm also one of their team-mates . I told them all individually and some of them were upset , but they did n't sulk .

`` It 's good to end the day as we did , scoring goals and creating chances , '' he added . `` I reminded the players the tempo needed to be quicker at half-time and they reacted well to that . ''

While delighted with the result , which was United 's first win since early April , Giggs also said he was equally pleased with his team 's performance .

United looked sharper , faster and more penetrative with their passing than they have in recent weeks , particularly after taking the lead .

Norwich had coped well up until then although the breakthrough arrived after some calamitous defending by the visitors .

Three Norwich players missed opportunities to clear a weak cross into the box before the ball fell to the feet of United striker , Danny Wellbeck , who was duly hauled down by Steven Whittaker as he was about to shoot .

Referee Lee Probert pointed to the spot and Wayne Rooney stepped up to send Norwich keeper John Ruddy the wrong way .

The second half began just as the first ended with Rooney pushing forward and curling a shot beyond Ruddy from 20-yards out .

Giggs then brought on Juan Mata who had dropped to the bench after last week 's defeat at Everton and the Spanish international made it 3-0 just after the hour , knocking in a Phil Jones cross .

Norwich were well beaten by this stage and a Mata header after Valencia fired across goal made it four shortly after .

Rooney and Javier Hernandez came close in the final ten minutes for United while a deflected shot from Norwich 's Leroy Fer rebounded off the bar but the game would finish without any further scoring .

Norwich remain a point above the relegation zone in 16th position with two games to play after Fulham blew a two goal lead at home to FA Cup finalists Hull City earlier in the day , spurning the chance to move above the Canaries .

Fulham were two up with 15 minutes to play thanks to second-half strikes from Ashkan Dejagah and Fernando Amorebieta but late goals from Hull 's Shane Long and Nikica Jelavic snatched a draw .

Elsewhere in England , West Brom took a step closer to Premier League survival with a 1-0 home victory over West Ham while Aston Villa 's poor run of form continued as they were defeated 4-1 at Swansea .

In Saturday 's lunch time kick-off , Everton 's Champions League hopes took a blow as they slumped to defeat at Southampton . Own goals from Everton defenders Antolin Alcatraz and Seamus Coleman were enough to seal a 2-0 victory for the Saints .

A victory for Tottenham at 10-man Stoke means they now trail fifth placed Everton by just three points .
